Subject: [sa]: Fix C++ regressions on structure-aliasing branch

This patch fixes the C++ regressions that were occuring on the structure
aliasing branch (more places where the fact that a structure field is
not a real variable, and not quite a memory tag, were important)
Bootstrapped and regtested on i686-pc-linux-gnu
Committed to structure-aliasing-branch.
